Definitions

the washing machine has become one of main household appliances in people's daily life
the washing process of the washing machine mainly includes washing, rinsing and spin-dry stages, in the washing stage, water and detergent flood in the washing machine to wash clothes, after the washing machine enters the rinsing stage, in order to rinse stains and residual detergents, it is necessary to take in more water or perform more rinsing times to rinse the clothes, this will definitely consume a large number of water resources, even if it is a water-saving roller washing machine, in order to clean the clothes, the clothes needs to be rinsed at least twice, and such a process will at least consume more than 30 L of running water.
a layer height of clear water and turbid water is determined after the flocculation treatment, the clear water is controlled to discharge though detecting flocculation water level after the flocculation treatment.
a washing machine of the present disclosure comprising a body of the washing machine and a water circulation processing system, wherein, the water circulation processing system comprises a flocculation container which is used for flocculation treatment of water discharged from the body of the washing machine, and flocculation container is provided with a water level detection means.
